Dogma London collars are available in six standard sizes with four width options, all listed below. We will also make any of our collars in a custom size if your dog's measurements fall between our standard sizes. Just ask!
To measure your dog for a martingale collar, use a soft tape measure and measure three points shown below.
Around the widest part of the head:
Behind the ears:
Around the neck (where the dog collar will sit):
Choose the smallest size dog collar that will still fit all three points. For example, if your dog has a 16" neck, select a medium sized dog collar (adjustable from 13-17") rather than a large, which is adjustable from 16-20 inches. Of course you can always just send us your three measurements and we can tell you what size of martingale dog collar will fit your pup perfectly!
To measure your dog for a buckle or tag collar, use a soft tape measure or ribbon. Measure around the middle of your dog's neck to determine the circumference, then add 2" to your measurement so that the collar is not too tight and is big enough to adjust.
Measurements are in inches. If your dog's neck measurements falls between two sizes, we can make a custom size at no charge. Just ask!
Our collars are available in four widths: 2 inches, 1.5 inches, 1 inch, and .75 inches. If any of the widths are not available for a particular pattern, it's because the print size of that pattern is too large to show up well on a narrower width. When choosing a width remember that generally, wider collars look best on dogs with long or large necks.
Sweet Tooth collar shown in four widths: .75 inches, 1 inch, 1.5 inches, and 2 inches.
Dogma London collars are adjustable to fit a range of neck sizes. If your dog needs a size not listed below, just ask! For help with measuring your dog for a collar, see our Measuring Guide.
